Features o your Tandem™ Hearing
Instruments
Tandem™hearing instruments come equipped with
various advanced features, including:
• CROS and BiCROS inputs
• Automatic listening program plus 3manual
programs for Tandem 16
•4manual programs for Tandem 4
• Speech enhancement LD
• AntiShock™
• Noise reduction
It may take some time for you to fully adjust to your new
hearing instruments. In the beginning, do not feel as
though you need to wear them for longer than is
comfortable. Depending on your previous experience with
hearing instruments, increase wearing time gradually until
you have fully adjusted to them. Eventually, you should
wear your Tandem hearing instruments all day every day.
Please consult your hearing healthcare professional
regarding any adjustments you may require to ensure
that you are happy with your hearing instruments. For
instance, pitch and loudness of the beeps can be
adjusted or turned off entirely. Also note that this is a
general guide and your hearing healthcare professional
may have enabled or disabled certain features
depending on your requirements.

Putting your Hearing Instruments on
your Ears
Your behind-the-ear (BTE) hearing instruments may be
color-coded red for your right ear and blue for your left
ear. This color indicator is located on the battery door
with a small colored dot. The transmitter hearing
instrument is for your poor ear and the receiver
hearing instrument with the receiver boot is for your
better ear.
BTEs with Earmolds
1. Hold the earmold between your thumb and index
finger. The opening should be pointing in towards
your ear canal with the BTE resting upwards near
the top of your ear. Carefully insert the earmold in
your ear. You may need to turn it slightly
backwards. The earmold should fit into your ear
snugly and comfortably.
2. Place the hearing instrument over the top of your
ear.

8
BTEs with Slim Tubes
1. Hold the slim tube where it attaches to the dome
and gently push the dome into your ear canal. The
slim tube should lie flush against your head and not
stick out.
2. Place the hearing instrument over the top of your
ear.
3. Place the retention piece in your ear so it rests at
the bottom of the opening of your ear canal.

9
Turning your Hearing Instruments On
and O
Your hearing instruments have a three-position
battery door or receiver boot that acts as the on/off
switch and that allows access to the battery
compartment.
ON:
To turn your transmitter hearing instrument on, close
the battery door fully.
To turn your receiver hearing instrument on, close the
receiver boot fully.
Note: It may take a few seconds befo e the
hea ing device tu ns on. You hea ing healthca e
p ovide can additionally inc ease the sta t up delay if
equi ed.
OFF:
To turn your transmitter hearing instrument off,
partially open the battery door.
To turn your receiver hearing instrument off, partially
open the receiver boot.
This position allows excess moisture to vent away
from the battery compartment.

Battery In ormation
Size 13 batteries are used in your Tandem hearing
instruments.
To replace the hearing instrument battery, fully open
the battery door or receiver boot for access to the
battery compartment.
Low Battery Warning
When you hear two long beeps, your hearing devices
are warning you that their batteries are low. You will
hear the warning approximately every 30 minutes
until you change the batteries or the batteries die.
After the first warning, you may experience some
reduction in sound quality. This is normal and can be
remedied by inserting fresh batteries into the hearing
devices. If you prefer, your hearing healthcare
professional can change the pitch and loudness of the
low battery beep or turn it off entirely.
Note: Replace the batte ies in both the
t ansmitte and eceive hea ing inst uments at the
same time.
Replacing the Battery
1. Gently swing out the battery door or receiver boot
with your fingernail.
2. Grasp the battery with your thumb and index finger
and remove.

3. Insert the new size 13
battery into the battery
compartment with the
plus (+) sign on the
battery facing up, the
same way as the plus (+)
sign on the edge of the
battery door. This will
ensure that the battery
door closes properly.
Note: If the batte y is inse ted inco ectly, the
doo will not close.
4. Close the battery door.
Caring or Batteries
• Always discard batteries in a safe and
environmentally friendly way.
• To prolong battery life, remember to turn your
hearing devices off when not in use.
• Remove the batteries and keep the battery door
and receiver boot open while your hearing devices
are not in use. This will allow internal moisture to
evaporate.

Setting your Ideal Volume
Your Tandem receiver hearing instrument has an ideal
volume indicator. A single beep indicates when the
volume control has reached its ideal level for your
particular hearing abilities, as pre-set by your hearing
healthcare professional.

14
Tandem™transmitter earing instrument wit

Your Tandem transmitter hearing instrument has a
volume control which only affects the sounds coming
from the poor ear side. You can increase the loudness
of sounds from your poor ear side by turning up the
transmitter volume control (scroll up). You can
decrease the loudness of sounds from your poor ear
side by turning down the transmitter volume control
(scroll down).
Note: The t ansmitte volume cont ol does not

15
Push Button
Your receiver hearing instrument is equipped with a
push button which enables you to switch between
programs. Each time you push the button, you will
move to a new program. Your hearing instruments
beep to indicate which program you are in (i.e. one
beep for program 1, two beeps for program 2, etc.). If
you prefer, your hearing healthcare professional can
change the pitch and loudness of the beeps or turn
them off entirely.
Your Tandem hearing instruments may also come with
an optional remote control which allows you to switch
between different listening programs. Please refer to
the Smart Control User Guide for more information.
Program 1 (e.g. Automatic Program) 1 beep
Program 2 (e.g. Group/Party Noise) 2 beeps
Program 3 (e.g. Easy-t/Telephone) 3 beeps
Program 4 (e.g. Music) 4 beeps
Easy-t/Telephone short melody

Using the Telephone
As telephones do not all work the same, you may
experience different results from different phones. You
can use many phones by simply holding the receiver
to your ear, without the need to change to a dedicated
telephone program on your hearing instrument.
Remember to move the handset slightly up or back to
find the position that sounds best to you.
Your hearing healthcare professional may have set up
an automatic telephone program on your Tandem
hearing instruments, called easy-t. Your hearing
instrument will automatically switch to your dedicated
telephone program when the telephone is brought up
close to your receiver hearing instrument (better ear).
When the telephone is moved away from the hearing
instrument, it will automatically return to the previous
listening program.
This automatic switching relies on the magnet in your
telephone ear piece. If the hearing instrument does
not switch to the telephone program automatically
when the telephone is placed close to your receiver
hearing instrument, then the magnet in your
telephone is not strong enough to trigger the
automatic switching. Ask your hearing healthcare
professional for an easy-t magnet and attach it to your
telephone ear piece.

17
Consult your hearing healthcare professional if you
experience difficulties using your hearing instruments
on the phone.
To affix t e optional easy-t magnet:
1. Clean the telephone ear piece.
2. Hold the magnet near the “listening end” of your
telephone and release it (Figure 1). The magnet will
flip to the appropriate side and seek the optimal
position on the telephone ear piece.
3. Place the double-sided tape in this optimal position
on the telephone ear piece (Figure 2) and attach
the magnet to the tape (Figure 3).

Caring or your Hearing Instruments
• Open the battery door and receiver boot when not
in use.
• Always remove your hearing instruments when
using hair care products. The hearing instruments
can become clogged and cease to function
properly.
• Do not wear your hearing instruments in the bath
or shower or immerse them in water.
• If your hearing instruments do become wet, do not
attempt to dry them in an oven or microwave. Do
not adjust any controls. Open the battery door or
receiver boot immediately, and allow your hearing
instruments to dry naturally for 24 hours.
• Protect your hearing instruments from excessive
heat (hair dryer, vehicle glove box or dashboard).
• Regular use of a dehumidifier, such as a Dri-Aid kit,
can help prevent corrosion and prolong the life of
your hearing instruments.
• Do not drop your hearing instruments or knock
them against hard surfaces.
